Testing. During testing, we use the same person detection results provided in [1]}, which are widely used for many single-person HPE models [2]}, [3]}. Single persons are cropped out according to the detection results and then resized and input to the HPE models. The flip test [2]} is also performed in all experiments. Each keypoint location is predicted by adjusting the highest heatvalue location with a quarter offset in the direction from the highest response to the second-highest response [2]}.
